Smaller capacitors such as Ceramic \u00a0capacitors often don’t have space to have the full spec written on them so they use a coding scheme to tell what they are.<\/p>\n
This coding is usually in 2 or 3 digits, sometimes followed by a letter that defines tolerance.<\/p>\n
For two digits: For three digits: Other formats: Tolerance:<\/strong><\/p>\n Sometimes the 2 and 3 digit capacitors also have a letter at back which represents the tolerance. The tolerance is coded as follows:<\/p>\n
\n<\/strong>You simply read them as pico-Farads (pf). So 10 would mean 10 pF<\/em>.<\/p>\n
\n<\/strong>You read the first two and then add the amount of zeros at back of the number as last digit says. So for example 101 would be 100 pF<\/em>. And 100 would be 10 pf<\/em>. (Yes sometimes same one can be represented either in 2 letter system or 3 letter system). 102 would be 1000 pF.<\/em><\/p>\n
\n<\/strong>You might also encounter capacitors that are coded like 2n0, which means they neither are in the 2 digit system nor the 3 digit system. 2n0 would mean 2.0 nF, where the n says the unit, which in this case was nano-Farad.<\/p>\n\n
